The invention relates to a far-infrared heating material, a preparation method of a far-infrared heating body and the far-infrared heating body. The far-infrared heating material comprises tin tetrachloride, tin oxide, antimony trichloride, titanium tetrachloride, copper sulfate pentahydrate, germanium chloride, hydrochloric acid and a solvent. Metal elements in tin tetrachloride, tin oxide, antimony trichloride, titanium tetrachloride, copper sulfate pentahydrate and germanium chloride have proper energy bands, and cooperate with the conductive film layer for use; after electrification, the outer-layer electrons of the metal elements obtain an energy band, the energy of which is transited to a relatively high energy level and then returns to the energy band with the low energy level, i.e., returning a stable state and generating far-infrared radiation. According to the invention, tin tetrachloride, tin oxide, antimony trichloride, titanium tetrachloride, copper sulfate pentahydrate and germanium chloride cooperate with each other, and energy band matching is generated among molecules of all the components; the interactive transition and mutual promotion are generated among electrons on the outermost layer of metal elements, the conversion efficiency of electric energy-heat energy is improved, energy consumption is reduced, and the heating effect is good.
